Detailed implementation manners

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-4 shown, a rice seedling transplanter that is convenient to use provided by an embodiment of the present utility model includes a frame body 1. The outer wall of one side of the frame body 1 is connected by bearings with driving rollers 2 distributed up and down. The outer wall of the other side of the frame body 1 is connected by bearings with driven rollers 3 distributed up and down. A conveyor belt 4 is drivingly connected between the driving roller 2 and the driven roller 3. Uniformly distributed seedling trays 14 are arranged on the top of the conveyor belt 4. One end of the driving roller 2 is fixed with a crank 5. A fixed sleeve 19 is embedded in the outer wall of the frame body 1 close to the driving roller 2. A movable column 22 is movably inserted into the inside of the fixed sleeve 19. One end of the movable column 22 is fixed with an extrusion column 20. One end of the extrusion column 20 extends to the outside of the fixed sleeve 19 and abuts against the driving roller 2. An installation groove 18 is arranged inside the fixed sleeve 19. A cam 21 is hinged inside the installation groove 18. The cam 21 is adapted to the movable column 22.

[0023] Specifically, in this embodiment, it includes a frame body 1. One outer wall of the frame body 1 is connected by bearings with upper and lower distributed driving rollers 2. The other outer wall of the frame body 1 is connected by bearings with upper and lower distributed driven rollers 3. A conveyor belt 4 is drivingly connected between the driving roller 2 and the driven roller 3. The driving rollers 2 and the driven rollers 3 at both ends of the conveyor belt 4 are at the same height. The top of the conveyor belt 4 is provided with evenly distributed seedling trays 14. The inside of the seedling trays 14 has rice seedlings. One end of the driving roller 2 is fixed with a crank 5. It is convenient to rotate the driving roller 2 through the crank 5. A fixing sleeve 19 is embedded in the outer wall of the frame body 1 close to the driving roller 2. An activity column 22 is movably inserted into the inside of the fixing sleeve 19. The activity column 22 can move inside the fixing sleeve 19. One end of the activity column 22 is fixed with a pressing column 20. One end of the pressing column 20 extends outside the fixing sleeve 19 and abuts against the driving roller 2, so that the pressing column 20 fixes the driving roller 2 by the pressing force. An installation groove 18 is arranged inside the fixing sleeve 19. A cam 21 is hinged inside the installation groove 18. The cam 21 is adapted to the activity column 22. When the cam 21 presses the activity column 22, at this time the pressing column 20 fixes the driving roller 2 by the pressing force. When the cam 21 rotates and is away from the activity column 22, at this time the abutment of the pressing column 20 against the driving roller 2 becomes loose, so that the driving roller 2 can rotate. An installation plate 12 is fixed inside the frame body 1. Between adjacent two installation plates 12, evenly distributed supporting rollers 13 are connected by bearings. The top of the supporting roller 13 is adapted to the driving roller 2. The top of the supporting roller 13 is flush with the top of the driving roller 2, so that the supporting roller 13 can support the conveyor belt 4, and further makes the conveyor belt 4 more stable when conveying the seedling trays 14.

[0024] For a rice seedling transplanting frame provided by the utility model, the driving roller 2 is rotated by the hand wheel 11, so that the driving roller 2 can drive the conveyor belt 4 to move, and the conveyor belt 4 can move the distant seedling trays 14 towards the operator. Since it is difficult for the operator to walk in the muddy paddy field, the number of times the operator walks is reduced, making it more convenient for the operator to take the distant seedling trays 14, and further making the transplanting frame more convenient to use.

[0025] In another embodiment provided by the utility model, a spring 23 is sleeved outside the pressing column 20. The spring 23 is located inside the fixing sleeve 19. When the cam 21 rotates and is away from the activity column 22, the spring 23 is used to move the pressing column 20 away from the driving roller 2. At this time, the pressing column 20 will not hinder the rotation of the driving roller 2.

[0026] In another embodiment provided by the present utility model, two support plates 6 are fixedly arranged on the outer wall of the top of the frame body 1. A shielding plate 8 is arranged on the top of the support plate 6. A support rail 9 is fixedly arranged on the outer wall of the bottom of the shielding plate 8. On the one hand, the support rail 9 can strengthen the shielding plate 8. The support rail 9 is slidably connected to one of the support plates 6. The shielding plate 8 can be used to shade or shelter the operator, preventing the operator from being exposed to the sun or rain. A screw rod 7 is connected between the two support plates 6 through a bearing. One end of the screw rod 7 penetrates through the support plate 6 and is fixedly provided with a hand wheel 11. The hand wheel 11 is used to conveniently rotate the screw rod 7. A slider 10 is fixedly arranged on the outer wall of the bottom of the shielding plate 8. The slider 10 is threadedly connected to the screw rod 7. Thus, by rotating the hand wheel 11, the shielding plate 8 can adjust the extended length according to requirements.

[0027] Furthermore, a sliding plate 15 is fixedly arranged at the bottom of the frame body 1. The number of the sliding plates 15 is preferably two, and the two sliding plates 15 are respectively located on both sides of the bottom of the frame body 1. When dragging the frame body 1, the frame body 1 can be slid in the paddy field through the sliding plate 15. The use of the sliding plate 15 can effectively prevent the frame body 1 from sinking in the paddy field. An arc-shaped plate 16 is integrally formed at one end of the sliding plate 15. A bracket 17 is fixedly arranged at one end of the sliding plate 15 away from the arc-shaped plate 16. The bracket 17 is used to hold the seedling tray 14 for transplanting rice seedlings.

[0028] Working principle: During use, the frame body 1 is slid in the paddy field through the sliding plate 15. Then, a seedling tray 14 is placed on the bracket 17. The operator stands on the side of the bracket 17 away from the frame body 1 and faces the frame body 1. At this time, the operator can transplant the rice seedlings on the bracket 17. When it is necessary to take the seedling tray 14 again, first rotate the cam 21 so that the cam 21 does not squeeze the movable column 22. At this time, the elastic force of the spring 23 drives the extrusion column 20 away from the driving roller 2. Then, rotate the driving roller 2 through the hand wheel 11, so that the driving roller 2 drives the conveyor belt to rotate. The conveyor belt conveys the seedling tray 14 towards the bracket 17. Thus, it is more convenient for the operator to take the seedling tray 14 at a relatively far distance. At the same time, drive the screw rod 7 to rotate through the hand wheel 11, so that the screw rod 7 can drive the slider 10 to move. The movement of the slider 10 drives the shielding plate 8 to extend from the top of the frame body 1 towards the operator, so that the shielding plate 8 can shade or shelter the operator.

[0029] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
